Whats the value of $var? Because it's a CCK field you may need to use $form[$var]['#type'] = 'hidden'; $form[$var]['#value'] = $nid; to avoid clearing elements CCK expects to find. (Side note: I would use 'value' instead of 'hidden') Nevets On 6/28/2010 9:46 AM, Jeff Greenberg wrote:
Hi. I am hooking a node form. The content type has a cck node reference field, and the form has a text field to select the node. In some cases, the user should not be allowed to select...the value should be forced. So I decide which field name to use based on the content type, and then change the text field to a hidden field like this:
$form[$var] = array(
'#type' => 'hidden', '#value' => $nid, );
The form comes up just fine. The problem is, when it is submitted, I receive:
*Fatal error*: Cannot unset string offsets in *sites\all\modules\cck\content.module* on line *1248*
Thanks,
